LOOM SHUTTLE RETAINER 0R CHECK /va pb/eoh L am arc/2e Patented Aug. 13, 1940 UITED STATES PATENT ()FFICE 3 Claims.

The invention relates to improvements in devices used for checking loom shuttles at theends of the fly and for yieldably holding them in place until the next pick is to occur, and the object of the invention is to provide an exceptionally simple and inexpensive device for this purpose, yet one which will be efficient and reliable, may be readily adjusted as required to obtain the desired amount of friction, and may be used with equal advantage upon box looms or Draper looms.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Figure 1 is a plan view showing the device for use at the right hand of a Draper loom, and a similar construction, but reversed, is employed for the left end.

Figures 2 and 3 are respectively back and front views.

Figures 4 and 5 are transverse sectional views on lines l i and 5- 5 of Fig. 1.

Figure 6 is a plan View of the: device used at the left end of a box loom.

Figures 7 and 8 are respectively a back View and a, front view of the device shown in Fig. 6.

Figure 9 is a horizontal sectional view on line 9-9 of Fig. '7.

I provide a horizontally elongated support which may be of the general form shown in Figs. 1, 2 and 3 for use on a Draper loom, or of the form illustrated in Figs. 6, 7, 8 and 9 for a box loom, said support being indicated by the reference character 16. One end of the support is provided with an opening 1 I for a pivot pin while the other end of said support may vary as to structure, according to the type of loom upon which the device is to be used.

An opening i2 is formed transversely through the support it and a cylindrical post i3 passes through said opening and projects from said support, adjusting nuts it being threaded on said post at opposite sides of said support to vary the extent which the post projects from the support.

An elongated shuttle check [5 extends. longitudinally of and is spaced from the support In,

and a pivot is connects one end of said check with the projecting end of the post [3 to mount said check for movement toward and from the support if The opposite end portion of the check i5 is provided with a U-shaped yoke ll which straddles the support Ill, and a set-screw i8 is threaded through the crown portion I9 of said yoke in position to abut said support ill to limit the movement of the check l5 away from said support. A suitable lock nut or the like 20 is provided for this set screw.

I have shown a spring arm 2| extending obliquely from the support In to the end of the check I 5 which is provided with the yoke ll, said spring being bolted or otherwise secured at 22 to said support and having its free end disposed against said check. I have shown a set screw 23 threaded through the support H3 and bearing against the spring 2! to vary the push of the latter against the check l5, and have also illustrated a lock nut 24 for said set screw 23.

The check l5 preferably consists of an elongated body 25 and a lining 26 of leather or other friction material at one side of said body to frictionally contact with the shuttle. At the end of the check which is first engaged by the shuttle as. it reaches the end of the race, the lining 26 is turned at 21 around the adjacent end of the body 25 and is fastened to the latter by a rivet or the like 28. The opposite end of the body 25 is preferably somewhat beveled at 29 and the adjacent end of the lining 26 is secured against the beveled surface by a rivet or other fastener 30.

By providing the novel construction shown and described, the device will be very effective to arrest the shuttle travel and to yieldably hold the shuttle until the next pick is to take place, and the device may be readily applied to looms of different kinds and easily adjusted to obtain the desired frictional braking and holding action.

As excellent results are obtainable from the details disclosed, they are preferably followed. However, within the scope of the invention as claimed, variations may be made.

I claim:

1. A shuttle check comprising an elongated support having an opening extending transverse ly therethrough, a post passing through said opening and projecting from said support, adjusting nuts threaded on said post at opposite sides of said support for varying the distance which said post projects from said support, an elongated shuttle check extending longitudinally of said support and spaced therefrom, means pivotally connecting one end of said check to the inner end of said post and. mounting said check for movement toward and from said support, a U-shaped yoke secured to the other end of said check and embracing said support, a set screw threaded through said yoke to abut said support and limit the movement of said check away from said support, spring means interposed between said support and said check for yieldably urging said check away from said support to the extent permitted by said set screw, and means for locking said set screw.

2. A structure as specified in claim 1; and means for adjusting said spring means to vary its strength.

3. A structure as specified in claim 1; said shuttle check comprising a rigid body, and a lining of friction material secured at its ends to said body.
